CURTAIN-ROD.

Application filed April 16, 1920.

To all whom it may concern Be it known that I, JAMES H. Born, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Curtain-Rods, of which the following is a specification.

This invention relates to improvements in curtain rods, and has reference more particularly, first, to an improvement in the form of the rod itself designed to afford greater strength and stiffness in the horizontal plane of the rod than is obtainable with the so-called hollow flat rods at present extensively used; and second, to provide a stiffening and locking device for a spring wire loop which I have heretofore used in the ends of the curtain rods to detachabl; lock the latter in the supporting brackets of the curtain fixture. I

That feature of the present invention which relates to an improvement in the form of the rod itself embodies, to a certain extent, the structural principle of the rod disclosed and claimed in my pending application, Serial No. 349,854, filed Jan. 7, 1920. In the said application, I have disclosed a telescoping rod ofthe flat type wherein the rear walls of the two telescoping rods are centrally slotted longitudinally and formed with inturned oblique marginal portions or flanges, the marginal portions of the inner rod bearing upon the marginal portions of the outer rod, and the front walls of the rods being substantially flat and lying in contact with each other. This construction affords a telescoping rod of great rigidity in a vertical. plane and one wherein the telescoping sections slideeasily upon each other with little friction. One object of the present invention is to provide a rod of this' general type which shall preserve the rigidity in a vertical plane and the easy sliding quality, and at the same time afford greater strength and rigidity in the horizontal plane of the rod.

Another object of the present invention, which has to do with curtain fixtures of the general type disclosed in my former Letters Patent No. 1,229,874, dated June 12, 1917, is to provide a combined guard and lock for the spring wire loop which forms a locking extension of the rod for engagement with a supportingbracket of the fixture.

In the accompanying drawing, I have illustrated the features hereinabove generally described, and referring theret0 Figure 1 is a front elevation of the upper portion of a window casing, showing my iming in rear elevation the spring wire loop in the end of the curtain rod and the combined guard and lock therefor;

Fig. 7 is an enlarged cross-section through the two telescopingrod sections.

Referring to .the drawing, 8 indicates the top and 9 the side members of an ordinary window frame or casing, on which latter are mounted curtain fixture brackets 10. Supported by and between the brackets 10 is is my improved curtain rod comprising the telescoping rod sections designated generally by 11 and 12. As best shown in Fig. 7, the larger rod section 11 is of generally triangular form in cross-section comprising a front wall 13 which is bent to present a broad horizontal V-shape in cross-section, rounded upper and lower edge walls 14, and flat wall sections 15 having the inwardly turned oblique free margins 16; all of said and bent to the shape sheet metal blank. The do not touch each other, longitudinal slot 17 in the rear wall of the rod.

The smaller rod section 12 has substantially the same shape as the larger section 11, but is sufficiently smaller in transverse dimensions to telescope within the latter. It is also folded and bent to form from a single sheet metal blank, and comprises the broad horizontal V-shaped front wall 18, rounded upper and lower edge walls 19, and flat rear wall sections 20 havingthe inwardly turned oblique free margins 21; the free edges of the latter being spaced apart and loop snaps into the holding socket of the forming between them a central narrow lonen'd bracket 10 in the manner shown in Flg.
